One of the core driving forces of this phenomenon is that the smash or pass model perfectly fits the human Social Comparison Theory, and the algorithm gamifies the process. Neuroscience research (the 2023 Nature Human Behaviour Report) indicates that when individuals receive rapid feedback on their appearance (typically presenting results within 300-500 milliseconds after the user’s operation), the peak activity intensity of their brain’s reward circuits (such as the nucleus accumbens) increases by an average of 40%. The growth rate of dopamine secretion can reach 200% of that in the resting state. This mechanism is similar to the Intermittent Rewards of slot machines. User behavior tracking shows that the median interval between two “tests” is 6.8 seconds (much lower than the 35 seconds for watching video content). The extremely high operation frequency density (approximately 8.8 clicks per minute) enhances user stickiness (with a median Session duration of 4.5 minutes). The cost-effectiveness of this immediate stimulus (the cost of a single server operation is approximately 0.0001) is far lower than that of developing complex games (with an average R&D budget of over 5 million).
Low participation threshold and Viral Loop Design are the keys to continuous diffusion. Users do not need complex operations (uploading pictures usually takes less than 3 seconds) or professional equipment (compatible with 100% smartphones), which is estimated to exceed 150 million global monthly active users in 2024 (estimated by Sensor Tower’s market model). The platform mechanism encourages sharing: The re-dissemination rate of user-generated result images on Instagram and TikTok is 23% (higher than the 15% of ordinary content), and each sharing can reach an average social network of 120 people (Facebook social graph research), with a viral coefficient greater than 1.2 (that is, one user can bring in more than one new user). By integrating algorithmic recommendations (platforms like TikTok allocate 3.5 times the weighted traffic to relevant hashtag Content), it drives topic hashtags to accumulate over 9 billion exposures within 18 months (official TikTok data), forming a self-reinforcing dissemination Cycle (Content Cycle).
The economic interest chain is deeply intertwined with the creator and developer ecosystem. The median quote for a single advertising collaboration promoting the smash or pass app by top creators (with more than 500,000 followers) is $2,200 (data from the Influence.co platform). In-app purchases (such as paying to unlock the advanced rating report at a unit price of 1.99) and advertisements (with an average CPM of 4.5) can generate a quarterly revenue peak of up to 3 million US dollars for developers (disclosed in the financial reports of some listed companies in Q1 2024). Free tools account for 89% in the App store (according to statistics from App Annie), but multiple revenue sources are formed through induced advertising (12 views per user per day), in-app purchase conversion rate (2.8% for paying users), and data licensing revenue (the premium for reselling user profiles to advertising platforms is approximately $0.03 per person) (ROI estimation exceeds 400%). This tripartite mutually beneficial model (with the platform taking a 30% cut, creators making profits, and developers generating revenue) ensures that resources are continuously invested in content production.
The Curiosity Gap about the unknown outcome and the attribute of Social Currency constitute the psychological engine. Psychological experiments (Journal of Experimental Psychology, 2023) show that when individuals are confronted with algorithmic “black boxes” (uncertainty index >0.7), the probability of their repetitive exploration behavior increases by 65%. Users are keen on sharing their personal smash or pass results in the community (for instance, a Discord channel adds 5.7 new discussions per minute), and scores or ratings become topics of social conversation (accounting for 62% in the survey of the youth group). Research indicates that sharing behavior increases the perceived Social connection strength of the sharer by approximately 30% (the change value of the Social Connectedness Index). Despite continuous controversies (such as the self-esteem injury lawsuit among teenagers in South Korea in 2023), this pattern still maintains a weekly activity rate of 57% among Gen Z (aged 16-24) users, driven by Mental Fluency and social integration pressure (GlobalWebIndex 2024 report). There are no signs of attenuation in the short term.
